      Today "no gui" snapshot have ssh.

      I will try but the last build is to short only 849668 Bytes (latest-nanobsd-vga-1g.img.gz  29-May-2014 23:36  849668), full seems ok.

      Updating my Hyper-V with 64 full.

      pfSense:
      ASRock -> Wolfdale1333-D667 (2GB TeamElite Ram)
      Marvell 88SA8040 Sata to CF(Sandisk 4GB) Controller
      NIC's: RTL8100E (Internal ) and Intel® PRO/1000 PT Dual (Intel 82571GB)

        2.2-ALPHA (i386)
        built on Thu May 29 06:53:30 CDT 2014
        FreeBSD 10.0-STABLE

        I am using the snapshot from the 29th and sshd doesnt start for me either.  If I run '/etc/sshd start' from the console it does start up like someone else mentioned.  If I kill it from the gui it stops.

        If I try to send a message to /var/run/check_reload_status unix socket using send_event("service restart sshd"); from the php 'Command Prompt' menu item under Diagnostics I see the log event that sshd was started but it doesn't actually start.  I don't believe it is executing sshd though because the SSH keys were never generated using the gui (which uses send_event()).  When I started sshd using the console with '/etc/sshd start' command though I saw the gui message system pop up an alert that the ssh keys were being generated.

        It seems like the problem is from /usr/local/sbin/check_reload_status or something that it doesn't do right.

        Note:  I applied the latest patches from several hours ago related to sshd before doing these tests.  I also rebooted just to make sure before doing the tests above.

          Don't know if this is helpful, but like my other posts stated….
          Reloading for any reason causes a loop that never resolves itself.
          I post here regarding OP's issue with SSH because in an attempt to get the GUI working I reverted to a snapshot from the 26th, and found the the reload still endlessly loops, even though I had mistakenly assumed everything was functioning okay from that early point.

            As I posted in another thread my CPU is at 100% all the time because of check_reload_status process eating it all.  The gui still seems functional for me.  Some things are slow at times though.  I really wish I could run an strace on check_reload_status like I do on programs running on Linux systems to see where it is spending it's time or look for errors in system calls.

              I haven't tried it but would this work?

                Thanks!  That is what I was looking for in freebsd.

                It looks like it is in an infinite loop trying to read from a bunch of file descriptors (or unix sockets?).  I don't know enough about check_reload_status to know what it is supposed to do but it seems like there is no data to read according to the = 0.  Maybe the wait time in the loop is not actually waiting for some reason.  It is eating 100% CPU just checking if data is available.

                I assume kevent is supposed to block (until some timeout) until data is available but it appears to be returning even when there is no data pretty quickly.

                kevent(4,{},0,{0x9,EVFILT_READ,EV_EOF,0,0x0,0x28824b60 0xb,EVFILT_READ,EV_EOF,0,0x0,0x28825560 0xd,EVFILT_READ,EV_EOF,0,0x0,0x28825f60 0xf,EVFILT_READ,EV_EOF,0,0x0,0x28826960 0x11,EVFILT_READ,EV_EOF,0,0x0,0x28827360 0x7,EVFILT_READ,EV_EOF,0,0x0,0x28824160 0x10,EVFILT_READ,EV_EOF,0,0x0,0x28827d60 0x13,EVFILT_READ,EV_EOF,0,0x0,0x28828760},64,0x0) = 8 (0x8)

                  Good news and bad news….

                  The good:
                  I updated to the latest snapshot from the 30th and now ssh works and check_reload_status doesn't eat up the CPU anymore!

                  The bad:
                  Now the gui doesn't work for me anymore.  I just get a timeout.  Doh.

                    It is getting a connection it seems.  If I go to the IP address using a browser instead of the name i get a certificate warning but then just a white screen with a waiting for IP message as the status waiting for data and eventually get a 'No data received' error from Chrome.
